How do i use the println statement to display the value of the language result?

In the video he did no specify how to incorporate the println statement with tuples.

tuples.swift
func greeting(person: String) -> (language: String,greeting: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)    
}

var result = greeting("Tom")
println result.language

When you construct result = greeting ("Tom"), you can check the language value in variable result by simply typing in "result.language". Then we can print that out. Hope this helps!!
